IMPROVEMENT IN MIDDLINGS-PURIFIERS.

Specification forming part of Letters Patent No. 1119,6S3,vdated April 14, 1874; application ile February 28, 1874.

To all whom 'it may concern:

Be it known that I, REUBEN Rornn, of Ephrata, in the county of Lancaster and State of Pennsylvania, have invented a new and Improved Middlings-Purier, of whi ch the following is a speciication The invention will rst be fully described, and then pointed out in the claim.

Figure lis a longitudinal sectional elevation of my improved middlings-puriier, taken on the line :v of Fig. 2. Figi is a transverse sectional elevation taken on the line y y, Fig. l; and Fig. 3 is a detail, in elevation, showing the method of operating the reciprocating sieve.

Similar letters of reference indicate corresponding parts.

A is the reel, which receives `the middlings through the spout B. C is a partition in the chest, cutting off returns before the middlings are taken' oft'. C! is the fan rblowing1 into the chest upon the reel to cool and clear it; D, chutes forming a hopper below the reel to discharge the lniddlings onto the reciprocating sieve E, and for preventing the blast from the fan below from blowing up into the reel-space.

F is the fan at the bottom of .the chest, blowing in through one side of the chest,up through the sieve E, and out at the other side through passage G, which is regulated by a valve, H, to control the blast. The fan F and the passage G are as long as the sieve, to cause the blast to act alikethroughout the length of the sieve, by whichthe action is uniform and very eiicient in separating the light fuzzy matters which do not contain flour, but discolor it when reground with the middlin gs. The sieve is operated by a cam-wheel, I, rock-lever J, and spring K, the cam being also the pulley for driving the conveyer L.

Having thus described my invention, I claim as new and desire -to secure by Letters Patent- 'The combination of fan C', reel A, hopper D, reciprocating sieveY E, fan F, and passage G, as and for the purpose specified.
